We sometimes find 45251 cast on the housing, and 40051 and 40052 stamped on the arm.

Description

The easiest way to determine the handing of your casement window unit is from the interior (inside) of the home. If you have multiple windows, stand in front of each window in question and locate the locks. The lock location will determine the handing of the unit.

All casement hardware, which includes locks, operators and hinges, are handed based on the lock location when viewed from the interior.
